These Strange Sounds were recorded in Fortaleza, Northeastern Brazil. Is it fake? I have a strange feeling (listen at the end of the video, the image stops and we heard the same sound three times in a row. Well, Tell me what you believe. In any cases, this sound is loud and very scary. The bad quality of the images makes this record even more apocalyptical. Yes it is strange. In the back you distinguish a distant siren. Are these the sound of a bird swarm? City sounds (you hear some cars and trucks). I also thought about glass bottles that are beeing brocken (glass recycling). Well this sound is difficult to debunk. What do you think it is?
